BRICK-MACHINE.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed October 26, 1912. Serial No. 727,992.

To all whom it may concern:

Be it known that I, CYRUS S. lVnn'r, a citizen of the United States,residing at Kendallville, in the county of Noble and State of Indiana,have invented certain new and useful, Improvements in Brick-Machines, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention comprehends certain new and useful improvements in brickor block machines of the multiple mold type and is designed particularlyfor use in the manufacture of concrete bricks, although it is to beunderstood that it is equally applicable for use with other plasticcompositions.

The invention has for one of its primary objects a simple, durable andefficient construction of brick machine, the parts of which are soformed and arranged that the molding operation may be very quicklyperformed, the bricks being formed face down in the mold and the moldbeing so mounted that it may be inverted and readily opened so as toexpose the completed bricks on the pallet.

A further object of the invention is a machine of this characterembodying improved pallet-holding devices and improved means forreleasing said pallet-holding devices preparatory to closing the moldagain after each molding and mold-inverting operation has beencompleted. And the invention also aims to generally improve devices ofthis class and to render the same more useful and commerciallydesirable.

With these and other objects in view, as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of. the invention, reference is to be had tothe following description and accompanying drawings, in which, V

Figure 1 is a front elevation of my improved molding machine, the partsbeing shown in closed position, but with the pallet holders in theirouter or inoperative positions. Fig. 2 is a detail perspective view of aportion of the mechanism employed for -moving the pallet holders toreleased position. Fig. 3 is a vertical transverse sectional Viewthrough the machine, parts being shown in side elevation. Fig. 4 is adetail perspective view of one of the division or partition plates whichform the mold into a plurality of compartments. Fig. 5 is a verticaltransverse sectional view through the machine with the moldopen and thebrick carriage in its inverted position. Fig. 6 is a detail longitudinalsection through the mold proper, designed particularly to illustrate themeans for holding the division plates in spaced relation to each other,Fig. 7 is a side elevation of the machine illustrating the parts in thepositions they assume after the brick carriage has been inverted and hasbeen started on its reverse movement to again close the mold. Fig. 8 is-a fragmentary perspective view of the brick carriage, and, Fig. 9 is adetail view illustrating particularly one means which may be employedfor slidingly mounting the hopper upon a platform extension of the mainframework of the machine.

Corresponding and like parts are referred to in the followingdescription and designated in the accompanying drawings by like.reference characters.

Referring to the drawings, the letter A designates the main frame-workof my improved machine, the same being of any desired construction ordesign suitable for supporting the actuating parts and for withstandingthe shocks incidental to tampiug and other operations characteristic ofmachinery of this class, said frame-work, in the present instance,embodying supporting legs 1 which preferably converge in an up 'warddirection and which are connected together by any desired number ofcross braces. The frame-work A embodiesmoldsupporting plates 2 which areriveted, bolted, or otherwise secured to the upper ends of the legs 1and through which any ;desired number of horizontally disposed tie rods3 extend, said tie rods being three in ,number in the present embodimentof the 100 invention. These tie rods support not only the end plates 1of the mold, but any desired number of intermediate or division plates 5which may be like the plates a in shape and construction. The plates 5are held in predetermined spaced relation to each other by means ofspacing sleeves or tubes 6 which are mounted upon the tie rods 3, asclearly illustrated in Figs. 5 and 6. The plates 5 are secured to avertically disposed and longitudinally extending back plate 7 in anydesired way, and for this purpose, in the present instance, I have shownthe division plates 5, as formed on their rear edges with tangs S whichare accommodated in apertures formed in the back plate 7 and which areupset after being inserted through said openings so as to practicallyform rivets, as clearly illustrated in Fig.

9 designates the front plate of the mold which is formed, as bestillustrated in Figs. 1 and S, with edge notches 10 designed in theupright or closed position of the plate 9 to receive the lugs llthat areformed on the upper forward corners of the division plates 5, wherebythe plate 9 will, in the closed position of the mold, effectually assistin holding the plates 5 stiff and properly in their respective planes.The front plate 9 is secured firmly to the preferably square portion 12of a longitudinally extending shaft 13 which is journaled at its ends inbearings formed by forward extensions of the base plates 2, as bestillustrated in Fig. 7, any desired number of bolts let serving as theconnecting means between the shaft and plate. Interposed between theattached edge of the plate 9 and the shaft 13 and held in place by thesame bolts 14, is a plurality of plate sections 15 which are equal innumber to the compartments that are formed between the division plates 5and of a size to snugly fit between said plates, the sections 15 beingslightly spaced from each other, as is manifest, and extendingsubstantially at right angles to the plate 9 and being adapted in theclosed condition of the mold, to rest solidly upon the spacing sleeves 6which encircle the tie rods 3. This is clearly illustrated in Fig. 3. Inorder to turn the shaft 13, it is provided at either or both ends withhandle rods 16.

The pallet 17 is designed to form the top of the mold when the latter isclosed and it also constitutes one of the elements of the brick carriagewhen the latter is inverted preparatory to removing the bricks. It maybe of any desired construction or design, and after being placed uponthe top of the mold, is held securely in position upon the plates sand 5by means of pallet holders 18 that comprise bars 19 pivotally mounted toswing laterally on transversely extending rods 20 mounted at the ends ofthe mold, said bars 19 being connected together at their relatively freeends by means of an angularly disposed transverse bar 21 designed toextend over and directly engage the pallet at the ends thereof. In orderto provide for pallets of different thicknesses, the bars 19 arepreferably formed in sections extensibly secured together by slot andbolt connections 22, as best illustrated in Fig. 8.

When the brick carriage is inverted preparatory to removing the moldedbricks, it is manifestly necessary to release the pallet holders 18 fromthe pallet before the pallet with the bricks thereon may be removed fromthe forwardly projecting frame extensions 23'on which the carriage isadapted to rest when in. its inverted position. To accomplish this, thepallet holders 18 are provided with transversely extending arms 24secured to the bars 19 in any desired way and projecting beyond one sideof the pallet holders, as clearly illustrated in the drawings. hen thebrick carriage is in an inverted position, the extensions of these arms24 will lie directly alongside of releasing pins 25 and 26 movablelaterally through bearings formed for them in the front legs 1 of theframe-work A. The pin is pivotally connected at its inner end to a rod27, said rod in turn being connected to one arm of a rocker bar 28pivotally connected, as at 29, to one of the legs 1. The pin 26 ispivotally connected directly to the other end of the rocker bar 28 andsaid rocker bar is formed with a crank 30 which is pivotally connectedto an actuating rod 31 which extends downwardly along one of the legs 1,as indicated in Fig. 1, said actuating rod being formed at its lower endwith an outwardly offset foot piece 32 working in a slot 33 formed insaid leg near the lower end of the latter. It will thus be under stoodthat after the carriage has been inverted and has come to rest with thepallet 17 directly supported upon the extension bars 23 of theframe-work, a pressure of the operators foot upon the foot piece 32 willmove the rod 31 downwardly and thereby swing the rocker bar 28 in adirection to force the releasing pins 25 and 26 outwardly against theextensions of the arms 24 and thereby swing the pallet holders 18 outfrom engagement with the pallet 17.

Preferably, in order to move the pallet 17 forwardly upon the extensionbars 23 so as to permit the front plate 9 to clear" the rear edge of thepallet and allow the mold to be closed after one molding and carriageinverted operation, Isecure to the front plate 9 by rivets or the like,presser fingers 341 which project from the relatively free edge of thefront plate and consequently, when the handle rod 16 is swung outwardlyto turn the shaft 13 and thus swing the block carried back to itsinitial position,

said fingers will engage the rear edge of the pallet and slide the sameforwardly upon the extension bars 23. This operation is clearlyindicated in Fig. 7

The hopper 35 of my machine is a boxlike structure without any bottomand is preferably provided with flared sides, and is mounted for aforwardly and rearwardly sliding movement upon a platform 36 whichextends rearwardly from the mold and which is supported by the mainframe-work in any desired way, as by struts or brace bars 37. Theplatform 36 is bounded at its ends by guide bars or rails 38, and thehopper is provided at its ends with depending slide bars 39 whichslidingly engage the rails 38, whereby the hopper is held securely for aback and forth movement and is not liable to become deranged.

In order to move the hopper, it is pivotally connected near its ends atthe rear side thereof with the upper ends of levers 40, said leversbeing fulcrumed intermediate of their ends on the braces 37 and beingpivotally connected at their lower ends with links 41. The links 41 arein turn pivotally connected to the angular side bars 42 of a foottreadle 43 which is in the form of an arched frame or bar pivotallyconnected at the ends of the side bars 42 with the rear legs 1, asclearly indicated at 44. It will thus be understood that when the foottreadle 43 is depressed. from the position just illustrated in Fig. 3 tothat illustrated in Figs. 5 and 7, the hopper 35 will be movedrearwardly from a position over the mold to a position upon its platform36. In order to return the hopper to its forward position, I preferablyprovide a handle rod 45 which is connected to the ends of the hopper andwhich extends across the front of the same. Preferably, contractilesprings 46 are provided to facilitate the operation of moving the foottreadle 43 upwardly when the handle 45 is grasped and the hopper movedfrom its rear position to its forward position over and upon the mold.

It is to be particularly noted that the hopper 35 has a scraper bar 45secured to its front side, whereby as the hopper is moved rearwardly,said bar will properly surface the concrete and scrape off all of thesurplus which will be carried within the hopper back upon the platform36. In the next succeeding forward movement of the hopper, this surplusconcrete still retained with in the'hopper will be carried forward anddropped into the otherwise empty mold.

From the foregoing description in connection with the accompanyingdrawings, the operation of my improved brick machine will be apparent.

After the block carriage has been swung upwardly and rearwardly to thelimit of its movement, with the plate sections 15 resting upon thesleeves 6 and with the front plate 9 properly engaging the front edgesand lugs 11 of the division plates 5, the hopper 35 is drawn forwardlyand is brought to rest over the mold, all surplus material removedduring the preceding molding operation being deposited in the otherwiseempty mold. The mold is then filled and the hopper moved rearwardly bydepressing the foot treadle 43, whereby the scraper plate 35 which issecured to the front of the hopper, as clearly illustrated in Figs. 1and 7, will scrape off all the surplus material and the same will becarried back upon the platform 36 and not be permitted to drop down toclog any of the operating parts or to drop upon the floor. After theplastic substance, for instance, concrete, has been tamped in anydesired way, preferably by an improved tamping mechanism which forms thesubject matter of a companion application executed of even dateherewith, the pallet 17 is placed in position over the mold andthe'holders 18 are swung inwardly to secure the pallet in position,after which the handle rod 16 is grasped and the carriage turned over tothe position illustrated in Fig. 5, after which the operator will placehis foot upon the foot piece 32 and force the pins 25 and 26 out againstthe extensions of the arms 24 of the holders 18 and thus free thepallet. The brick carriage can now be returned to its initial positionby drawing the handle rod 16 forwardly and upwardly, and during itsmovement, the fingers 34 will engage the rear edge of the pallet andwill slide the pallet forwardly on the extension bars 23 of theframe-work A.

While the accompanying drawings illustrate what I believe to be thepreferred embodiment of my invention, it is to be understood that theinvention is not limited thereto, but that various changes may be madein the construction, arrangement and proportions of the parts withoutdeparting from the scope of the invention, as defined in the appendedclaims.
